Abstract

An implantable heart defibrillator contains a pulse generator controlled by a control unit for emitting a number of heart stimulation pulses at a rate of several Hertz or more. The control unit causes the pulse generator to emit heart stimulation pulses with an energy content of the same, or somewhat greater, magnitude than conventional pacemaker pulses for a period of time long enough for the entire heart to become refractory.
